TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, in particular to a drainage system and pipeline arrangement method based on BIM technology. BACKGROUND

[0002] The building drainage system, especially the drainage system of the large basement roof, is the key project to ensure the safety of underground space structure and prevent leakage and water damage. The siphon drainage system is widely used in the drainage engineering of the garage roof due to its high drainage efficiency and relatively simple construction. The system is usually composed of drainage special-shaped pieces, drainage pipe networks, air vents, etc., and the siphon effect is used to quickly remove the seepage water in the top plate soil layer, which is crucial to protect the safety of the top plate structure.

[0003] However, the current siphon drainage system still has some deficiencies in actual application. Specifically as follows: the construction environment of the garage roof is extremely complex, after laying the drainage special-shaped pieces, subsequent cross operations such as soil backfilling, large plant planting, garden ornament construction and road paving are needed. In this process, the sharp stone and construction waste mixed in the backfilling soil can easily pierce or scratch the geotextile on the surface of the drainage special-shaped piece, and / or the heavy machinery (such as excavators, loaders and road rollers) directly passes and operates on the soil layer above the special-shaped piece, and the huge concentrated load generated by the heavy machinery can easily cause the adhesive part of the geotextile on the surface of the drainage special-shaped piece to separate. Further, in the operation process of the system, the fine particles (silt) in the soil can enter the drainage channel with the water flow, and over time, the effective water cross section of the drainage channel will gradually decrease until it is completely blocked, so that the siphon drainage system completely loses the drainage function and may cause the risk of basement roof leakage.

[0004] Therefore, in the operation of the siphon drainage system of the garage roof, how to prevent the silt from blocking the drainage channel and improve the reliability, durability and maintainability of the drainage system is a technical problem to be solved in the prior art. SUMMARY

[0016] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present application are: 1. The drainage system based on BIM technology, the silt collecting component is arranged in the U-shaped groove segment. When the silt collecting component is in the first form, the silt collecting plate is located at one side of the bottom of the U-shaped groove segment, and the water flow is sucked into the U-shaped groove segment, and the silt is deposited on the silt collecting plate. When the silt collecting plate collects more silt, the pull rod is pulled upward, the silt collecting plate moves to the first mud baffle area with the silt, and the silt collecting plate and the top of the U-shaped groove segment form a closed containing cavity, and the silt collecting component changes to the second form. Then water is injected into the containing cavity through the flow channel of the pull rod, and the silt on the surface of the silt collecting plate falls off under the impact of the water flow and flows out to the external environment through the air pipe and / or the flow channel of the pull rod, thereby realizing the cleaning of the silt in the siphon pipe, improving the reliability, durability and maintainability of the drainage system. In this embodiment, after the silt collecting component changes to the second form, the silt is in the closed containing cavity formed by the combination of the silt collecting plate and the top of the U-shaped groove segment, which can avoid the silt flowing into other parts of the U-shaped groove segment again during the cleaning process, and ensures the cleaning effect; 2. The drainage system based on BIM technology, the stopper cover and the pull rod are threadedly connected, and the stopper cover can change the fixed height on the pull rod by screwing. In the operation of adjusting the silt collecting component to form the second form, the stopper cover is moved to the pipe opening part of the air pipe and abuts against the air pipe, so that the silt collecting plate is fixed. By adopting this structure, after the silt collecting component is adjusted to the second form, the stopper cover is counterclockwise screwed to move downward along the threads of the pull rod until it tightly abuts against the pipe opening of the air pipe. At this time, the stopper cover can fix the silt collecting plate, ensuring the stability of the position of the silt collecting plate during the cleaning process, and providing good conditions for the silt cleaning operation. In this embodiment, the position of the silt collecting plate is fixed by the stopper cover, which also improves the convenience of the present application in use. On the other hand, during the silt cleaning operation, the stopper cover can also close the opening of the air pipe to prevent the water flow and silt from accidentally overflowing from the air pipe and polluting the environment, further improving the practicality of the present application; 3. The drainage system based on BIM technology, the second fender and the second mudguard are arranged on one side of the bottom of the U-shaped groove segment, when the pollution collecting part is in the first mode, the pollution collecting plate abuts against the second fender, the pollution collecting plate falls within the range of the second mudguard as a whole, and a closed cavity structure is formed between the pollution collecting plate and the basement top plate, at this time, the top end of the pull rod on one side is connected with a high-pressure water source through an interface, and the top end of the pull rod on the other side is connected with a negative pressure suction device; under the combined action of high-pressure water flow and negative pressure suction, the silt collected at the bottom of the pollution collecting plate can be discharged, effectively avoiding the accumulation of a large amount of silt in the cavity at the bottom of the pollution collecting plate, and further improving the effectiveness of silt cleaning in the siphon pipe.

[0025] Example 1: As Figures 1 to 4 As shown, the drainage system based on BIM technology of the present invention includes a siphon pipe 1, a drainage shaped plate 2, and a water collection module 3. The siphon pipe 1 is attached to the waterproof layer of the basement roof slab, and a water inlet channel 20 is provided on the side of the siphon pipe 1. The siphon pipe 1 divides the basement roof slab into several rectangular water filtration zones, and the drainage shaped plate 2 is laid in the water filtration zones. The surfaces of the siphon pipe 1 and the drainage shaped plate 2 are also provided with geotextile 4 for filtering silt. The siphon pipe 1 is connected to the water collection module 3, and a siphon effect is formed in the siphon pipe 1 during the process of water flowing into the water collection module 3. The siphon 1 is spliced by a plurality of U-shaped groove segments 5, each of which is internally provided with a dirt collecting component 6, and the top of the U-shaped groove segment 5 is vertically provided with a gas permeable pipe 7, the length of which is greater than or matches the thickness of the topsoil layer of the basement roof surface; the dirt collecting component 6 comprises a dirt collecting plate 8 and two pull rods 9, the length of the dirt collecting plate 8 matches the length of the U-shaped groove segment 5, and the width of the dirt collecting plate 8 matches the slot width of the U-shaped groove segment 5; the pull rod 9 is respectively arranged at both ends of the dirt collecting plate 8, the pull rod 9 penetrates out of the gas permeable pipe 7, and the pull rod 9 is further provided with a blocking cover 10 for closing the opening of the gas permeable pipe 7; The top of the connection between the two U-shaped groove segments 5 is further provided with a first mudguard 11, the inside of the pull rod 9 is provided with a flow channel 21, and the end of the pull rod 9 connected with the dirt collecting plate 8 is provided with a dirt outlet hole 12; The dirt collecting component 6 has a first form and a second form, When the dirt collecting component 6 is in the first form, the dirt collecting plate 8 is located at one side of the bottom of the U-shaped groove segment 5; Pulling the pull rod 9 upwards to move the dirt collecting plate 8 within the range of the first mudguard 11, and when the dirt collecting plate 8 is fixed and combined with the top of the U-shaped groove segment 5 to form a closed containing cavity, the dirt collecting component 6 changes to the second form; at this time, water is injected into the containing cavity formed between the U-shaped groove segment 5 and the dirt collecting plate 8 through the flow channel 21 of the pull rod 9, under the scouring of the water flow, the mud and sand on the surface of the dirt collecting plate 8 falls off, and the fallen mud and sand overflow into the external environment through the gas permeable pipe 7 and / or the flow channel 21 of one of the pull rods 9.

[0026] The application discloses a drainage system based on BIM technology, wherein the silt collecting part 6 is arranged in the U-shaped groove section 5. When the silt collecting part 6 is in the first mode, the silt collecting plate 8 is located on one side of the bottom of the U-shaped groove section 5, and the water flow is sucked into the U-shaped groove section 5, and the silt is deposited on the silt collecting plate 8. When the silt collecting plate 8 collects a large amount of silt, the silt collecting plate 8 is pulled upwards, and the silt collecting plate 8 carrying the silt is moved to the area of the first mud baffle 11, and the silt collecting plate 8 is combined with the top of the U-shaped groove section 5 to form a closed containing cavity, and the silt collecting part 6 is changed into the second mode. Then, water is injected into the containing cavity through the flow channel 21 of the pull rod 9, the silt on the surface of the silt collecting plate 8 is washed off under the impact of the water flow, and the silt is overflowed to the external environment through the air pipe 7 and / or the flow channel 21 of the pull rod 9, so that the silt in the siphon 1 is cleaned, and the reliability, durability and maintainability of the drainage system are improved. In the embodiment, when the silt collecting part 6 is changed into the second mode, the silt is in the closed containing cavity formed by the combination of the silt collecting plate 8 and the top of the U-shaped groove section 5, so that the silt is prevented from flowing into other parts of the U-shaped groove section 5 again during the cleaning process, and the cleaning effect is ensured.

[0027] Specifically, in the embodiment, when the silt in the siphon 1 is cleaned, the pull rod 9 is pulled upwards by hand, and the silt collecting plate 8 in the pull rod 9 is slowly lifted. At this time, the silt deposited on the silt collecting plate 8 is lifted. When the silt collecting plate 8 is lifted to the area of the first mud baffle 11, a high-pressure water source is connected to the interface at the top end of one of the pull rods 9. The high-pressure water source is started, and the clean water is sprayed out from the drain hole 12 at the bottom end of the flow channel 21 in the pull rod 9 at high speed, and the silt is quickly washed off from the silt collecting plate 8. Since the silt collecting plate 8 and the top of the U-shaped groove section 5 form a closed containing cavity, the washed-off silt can only be discharged to the external environment along with the water flow through the air pipe 7 and the flow channel 21 of the pull rod 9 on the other side.

[0028] In another embodiment, the high-pressure water source can be connected to the interface at the top end of one of the pull rods 9, and the negative pressure suction equipment can be connected to the interface at the top end of the other pull rod 9. Under the combined action of the high-pressure water flow and the negative pressure suction, the silt can be accelerated to be washed off from the silt collecting plate 8 and discharged to the external environment, and the cleaning efficiency is improved. Moreover, such an operation mode can also prevent the silt from polluting the external environment.

[0029] It should be noted that in the embodiment, the two ends of the silt collecting plate 8 are made of flexible rubber material, and when the silt collecting plate 8 is moved to the range of the first mud baffle 11, the flexible rubber is slightly deformed, so that the feasibility of the silt collecting part 6 forming the second mode is ensured.

[0030] Example 2: Figures 2 to 4 As shown, the drainage system based on BIM technology of the present invention, based on the above method, further includes a threaded connection between the sealing cover 10 and the lifting rod 9, and the fixed height of the sealing cover 10 on the lifting rod 9 can be changed by turning the sealing cover 10; in the operation of adjusting the sludge collection component 6 to form the second form, the sealing cover 10 is moved to the opening of the vent pipe 7 so that it abuts against the vent pipe 7, which can fix the sludge collection plate 8.

[0031] Specifically, in this embodiment, after adjusting the sludge collection component 6 to the second configuration, the sealing cap 10 is turned counterclockwise, causing it to move downwards along the thread of the lifting rod 9 until it tightly abuts against the opening of the vent pipe 7. At this time, the sealing cap 10 can fix the sludge collection plate 8, ensuring that the sludge collection plate 8 is stable in position during the cleaning process, providing good conditions for the sludge cleaning operation. Furthermore, in this embodiment, using the sealing cap 10 to fix the position of the sludge collection plate 8 also improves the convenience of the invention in use; on the other hand, during the sludge cleaning operation, the sealing cap 10 can also close the opening of the vent pipe 7, preventing water and sludge from accidentally overflowing from the vent pipe 7 and polluting the environment, further improving the practicality of the invention.

[0032] As a preferred embodiment, based on the above method, a first baffle 13 is further provided in the U-shaped groove segment 5, which is used to limit the height of the sludge collection plate 8 when it is lifted upward.

[0033] In this embodiment, during the operation of adjusting the sludge collection component 6 to the second form, the sludge collection plate 8 will stop rising when it contacts the first baffle 13. At this time, the sludge collection plate 8 is in the optimal position to form a closed receiving cavity with the top of the U-shaped groove segment 5. This ensures both a sealing effect and allows the water flow to effectively flush within the receiving cavity, ensuring the cleaning effect of mud and sand. At the same time, the setting of the first baffle 13 can also indicate to the operator that the sludge collection plate 8 has reached the appropriate height and formed the second form, further improving the practicality of the invention in actual use.

[0034] In practical applications, the first baffle 13 can be made of a high-strength, corrosion-resistant flexible material to adapt to the working conditions of the drainage system in a humid environment for a long time, ensuring that it can play a stable role for a long time.

[0035] As a preferred embodiment, based on the above method, the cross-sectional shape of the sludge collection plate 8 is further configured as an arc structure, and in the first form, the height of the water inlet channel 20 of the sludge collection component 6 is greater than the height of the sludge collection plate 8.

[0036] In this embodiment, the arc-shaped sludge collection plate 8 provides a larger deposition area, making it easier for silt and sand in the water flow to adhere and settle. Simultaneously, the height of the water inlet channel 20 is greater than the height of the sludge collection plate 8, ensuring that when the water flows into the U-shaped channel segment 5, it naturally carries the silt and sand towards the sludge collection plate 8, rather than directly bypassing it, thus ensuring the effectiveness of the sludge collection plate 8 in collecting silt and sand.

[0037] As a preferred embodiment, based on the above method, the length of the vent pipe 7 is further matched with the thickness of the soil cover layer on the surface of the basement roof slab. This structural arrangement avoids the vent pipe 7 affecting the planning of the ground functional areas, ensuring the effective utilization of ground space. Simultaneously, during periods of heavy rainfall, removing the sealing cap 10 and the plug at the top of the lifting rod 9 allows the siphon pipe 1 to directly connect with the atmosphere, enabling rainwater to flow into the siphon pipe 1 through the vent pipe 7 and / or the lifting rod 9, thus improving drainage efficiency.

[0038] As a preferred embodiment, based on the above method, a support plate 14 is further provided at the location of the U-shaped channel segment 5 corresponding to the water inlet channel 20. The support plate 14 is used to create a gap between the water inlet channel 20 and the geotextile 4. This structural arrangement can improve the smoothness of water flow into the U-shaped channel segment 5.

[0039] Example 3: As Figures 2 to 4 As shown, the drainage system based on BIM technology of the present invention, based on the above method, further includes a second mudguard 15 at the connection of the two U-shaped channel segments 5, and a second baffle 16 on one side of the bottom of the U-shaped channel segment 5. In the first configuration, the sludge collection component 6 has the sludge collection plate 8 abutting against the second baffle 16, the sludge collection plate 8 entirely falling within the range of the second mudguard 15, and the sludge collection plate 8 forming a gap with the surface of the basement ceiling. The sludge collection plate 8 is provided with a through hole 17, and the lifting rod 9 passes through the through hole 17. The lifting rod 9 can slide up and down within the through hole 17. The lifting rod 9 is also provided with a first plug 18 and a second plug 19 at intervals. The first plug 18 is located at the end of the lifting rod 9, and the sludge discharge hole 12 is located between the first plug 18 and the second plug 19. In the first form, the second plug 19 blocks the through hole 17 on the sludge collection plate 8; in the second form, the first plug 18 blocks the through hole 17 on the sludge collection plate 8.

[0040] In the above-described embodiments of the present invention, the cross-sectional shape of the sludge collection plate 8 is set as an arc structure. When the sludge collection component 6 forms the first form, a cavity is formed between the sludge collection plate 8 and the basement roof slab. During the process of collecting mud and sand using the sludge collection plate 8, water flow will carry some mud and sand from the gap between the two sludge collection plates 8 and fall into the cavity. Furthermore, during the process of the sludge collection component 6 changing from the first form to the second form, when the sludge collection component 6 forms the second form and cleans the mud and sand on the sludge collection plate 8, water flow will also carry some mud and sand from the gap between the sludge collection plate 8 and the U-shaped groove segment 5 and fall into the cavity. Over time, a large amount of mud and sand will accumulate in the cavity, causing the flow channel 21 area of ​​the U-shaped groove segment 5 to shrink, which will also affect the normal operation of the sludge collection component 6.

[0041] To address the aforementioned issues, in this embodiment, a second baffle 16 and a second mudguard 15 are provided on one side of the bottom of the U-shaped groove segment 5. In the first configuration, the sludge collection component 6 has the sludge collection plate 8 abutting against the second baffle 16, and the entire sludge collection plate 8 resting within the range of the second mudguard 15. A closed cavity structure is formed between the sludge collection plate 8 and the basement ceiling. At this time, a high-pressure water source is connected to the top interface of the lifting rod 9 on one side, and a negative pressure suction device is connected to the top interface of the lifting rod 9 on the other side. Under the combined action of the high-pressure water flow and the negative pressure suction, the sludge collected at the bottom of the sludge collection plate 8 can be discharged, effectively preventing a large accumulation of sludge in the cavity at the bottom of the sludge collection plate 8, and further improving the effectiveness of sludge cleaning in the siphon pipe 1.

[0042] As a preferred embodiment, based on the above method, further, when the second plug 19 seals the through hole 17 on the sludge collection plate 8, there is a gap between the end of the lifting rod 9 and the basement ceiling. With this structural arrangement, the second plug 19 can more effectively seal the through hole 17 on the sludge collection plate 8, preventing mud and sand on the sludge collection plate 8 from falling into the cavity below the sludge collection plate 8 through the through hole 17.

[0043] As a preferred embodiment, based on the above method, both the first plug 18 and the second plug 19 are further configured as frustum structures.

[0044] Example 4: Figures 1 to 5 As shown, the pipeline layout method based on BIM technology of the present invention includes the following steps: S1. Constructing a BIM model: Using BIM software, based on the architectural design drawings, structural design drawings, and actual on-site survey data of the basement roof slab, construct a three-dimensional BIM model of the basement roof slab. S2, Siphon drainage system modeling: Based on the constructed basement roof three-dimensional BIM model, according to the design scheme of the siphon drainage system, the siphon pipe 1, drainage special-shaped piece 2, water collection module 3 and other components are added to the model; the size, position and connection relationship of each component are calculated; S3, Collision detection and optimization: using BIM software to detect the collision between the drainage system model and other structures of the basement roof, check whether there is a space conflict or interference, adjust the pipeline layout scheme of the drainage system, and optimize the position and direction of each component; S4, Generating construction drawings: according to the optimized BIM model, producing each component of the siphon drainage system, and generating construction drawings containing the installation position information of each component according to the model; S5, Siphon drainage system construction: according to the generated construction drawings, using the above-mentioned drainage system components for installation and construction.

[0045] In this embodiment, in the stage of building BIM model, by combining architectural design drawings, structural design drawings and actual site survey data, the actual situation of the basement roof can be accurately restored, providing a solid foundation for subsequent drainage system modeling.

[0046] In the siphon drainage system modeling, the size, position and connection relationship of each component are accurately calculated, which helps to ensure the accuracy and rationality of the drainage system in actual installation.

[0047] In the operation of collision detection and optimization, the space conflict or interference between the drainage system and other structures of the basement roof can be found in advance. By timely adjusting the pipeline layout scheme and optimizing the position and direction of each component, the rework and modification in the construction process are avoided, which greatly improves the construction efficiency and reduces the cost.

[0048] When generating construction drawings, according to the optimized BIM model, not only the siphon drainage system components that meet the requirements of the construction site can be produced, but also detailed construction drawings containing the installation position information of each component can be generated. This makes the construction personnel have a basis in the installation and construction process, reduces the construction error, and improves the construction quality.

[0049] In the siphon drainage system construction stage, according to the generated construction drawings for installation and construction, the installation of the drainage system can meet the design requirements, and the normal operation of the drainage system can be ensured. At the same time, in the construction process, BIM model can be used for construction progress management and quality control, real-time monitoring of construction situation, and timely discovery and solution of problems.

[0050] In addition, the method can also be combined with other construction management systems to realize information sharing and collaborative work.
